I've never been to Puerto Rico and am thinking about going over Thanksgiving this year. Thinking about Old San Juan and Fajardo. If anyone has any suggestions for places to go or things to do while we're there I would really appreciate it! I definitely want to do the bioluminescent bay since it will be a good time to see it (based on the moon). I've heard they have pretty cool caves and waterfalls to swim in. Is the snorkling good? Thanks for any ideas!
